Sin Salida ("Spanish for "No Exit") was a professional wrestling major event produced by Consejo Mundial de Lucha Libre (CMLL) that took place on June 6, 2010, in Arena México, Mexico City, Mexico. The event was centered on the storyline between CMLL wrestlers and a group called Los Invasores, a group portraying an "invading force". The event featured six matches, where four of the six matches featured the Invasores group of wrestlers. CMLL usually hold their major events on Friday Nights, but in this case CMLL chose to hold the event on Sunday, running opposite their rival Asistencia Asesoría y Administración's Triplemanía XVIII event that took place on the same night in Mexico City. The main event was scheduled to be a Lucha de Apuestas, hair vs. hair match between Taichi vs. Máximo. Production Background The Mexican wrestling company Consejo Mundial de Lucha Libre (Spanish for "World Wrestling Council"; CMLL) has held a number of major shows over the years using the moniker Sin Salida ("No Ext" or "No Escape"). CMLL has intermittently held a show billed specifically as Sin Salida since 2009, primarily using the name for their "end of the year" show in December, although once they held a Sin Piedad show in August as well. All Sin Salida shows have been held in Arena México in Mexico City, Mexico which is CMLL's main venue, its "home". Traditionally CMLL holds their major events on Friday Nights, which means the Sin Salida shows replace their regularly scheduled Super Viernes show. The 2010 Sin Salida show was the second show to use the name. Storylines The event featured six professional wrestling matches with different wrestlers involved in pre-existing scripted feuds, plots and storylines. Wrestlers were portrayed as either heels (referred to as rudos in Mexico, those that portray the "bad guys") or faces (técnicos in Mexico, the "good guy" characters) as they followed a series of tension-building events, which culminated in a wrestling match or series of matches. On April 12, 2010, a contingent of former AAA wrestlers including Psicosis II, Histeria, Maniaco, El Alebrije and Cuije appeared on a CMLL show in Puebla, Puebla. The group drown into the arena in a black SUV and attacked La Sombra, El Hijo del Fantasma and La Máscara after they just finished wrestling. Brazo de Plata, Místico and Jon Strongman tried to help out but were kept away by CMLL rudos Averno,
